ThinkPad W520 uses Intel core i7-2720M processor, core frequency is 2.2GHz, four core eight thread.Memory, W520 uses a 4GB capacity Elpida particles DDR3-1333 memory, sequential 9-9-9-24.The hard disk, W520 with a block from Hitachi HTS725032A9A 2.5 inch 320GB 7200 RPM hard, average and burst read rate were 81.9MB/s, 150.9MB/s, seek time is 17ms, the overall transmission curve is very smooth, no large fluctuations.

Graphics, ThinkPad W520 uses NVIDIA Quadro 1000M, the card is full support for DirectX 11 characteristics, the top support up to 4GB of memory (Quadro 5000M), and the OpenGL version and Shader version of Model will rise to the new standard.At the same time, NVS also supports NVIDIA and chi (OPTIMUS) technology, automatic management of battery life and performance, according to the performance requirements in the core graphics card and the independent obviously card between intelligent switch, effectively increase the work efficiency for users at the same time the notebook battery life.

From the Windows 7 experience points we can see, the overall score to see first single channel memory caused a portion of memory low scoring results, at the same time as the desktop properties is used inside the processor core graphics card, so the relative frequencies of the lower core i7-2720 this slightly off, only obtained 4.7 points.In addition to the 7200 rotating disk is tie-in, believe that purse rich buyers will direct the choice of replacement for solid state disk.

In the final game test link, the default settings, "Street Fighter 4" 1366x768 resolution under the average rate was 96.02, 1024x768 resolution is 107.97; "Resident Evil 5" 1366x768 resolution under the average rate was 33.3, 1024x768 resolution is 68.5; "Lost Planet 2" 1366x768 resolution under the average rate of 17.5, 1024X768 resolution is 20.1.

Endurance, W520 equipped with 10.8V 8700mAh 9 core lithium battery.In the Imtec Battery Mark test, load test results for 3 hours and 44 minutes, a typical endurance test can only run a little more than 4 hours.

Heat, ThinkPad W520 in the bottom of the eight cooling holes, respectively, each part provides separate air inlet holes, then unified processor from the exhaust outlet outside of the body.From the point of view of the distribution of the thermal imager, ThinkPad W520 in standby heat under the main distribution is in the left side of the cooling holes, but under the condition of full load W520 maximum temperature less than 40 degrees.

In the understanding of the ThinkPad W520 hardware configuration and the basic properties, we can have a look at the appearance of it.

W520 uses a high elastic composite polyethylene material, this material has a lighter, stronger, more conducive to the wireless signal transmission, and no deformation and handle delicate features.While the bottom of the carbon fiber composite material has high strength, heat resistance, thermal shock, low thermal expansion coefficient, small specific gravity and resistance to corrosion and radiation characteristics.At the same time, W520 A is a continuation of the T series of classic magnesium roll cage, reduced from the external 30% impact force, enhance the body's stability.

W520 uses a 15.6 inch 1920 x 1080 resolution LED screen, screen the maximum opening angle of 180 degrees.At the top of the screen, a 1300000 megapixel camera, support 1280x720 resolution video transmission.

The keyboard is still in traditional ThinkPad bond distance of 18.5-19mm, key 1.8mm-2.5mm deep this layout to design, "and" structure of the IBM Thinkpad T22 Laptop Keyboard as compared to the previous "X" structure provides better tactility softness and elasticity, keys.Touch panel using the pointing stick (TackPoint) and touch panel (TouchPad) UltraNav dual pivot system.

Interface, the left side of the machine body configured Display Port interface, VGA interface, 2 USB3.0 interface, Power eSATA, WiFi switch.It is the right Express Card 2 interface, composite audio interface, drive, IBM LENOVO Thinkpad X60s X61s CMOS Battery 92P1210, RJ-45; while the fuselage behind is only provided with a charging interface of USB shutdown.

Summary

Although ThinkPad W520 as W510 products in appearance and interface with almost no change, but it uses the latest Intel SandyBridge processor and NVIDIA new Quadro 1000M professional mobile graphics cards, so the inner aspect compared to W510 or improve a lot.

W series of products as the current ThinkPad notebook products in the top mobile workstation product series, in the technology and equipment represented the highest level of ThinkPad, so with a new start again W520 can reach ThinkPad for W series "than the muzzle bullet faster" requirement, but if you choose the product, whether it is the durability and reliability of speaking, users will experience the top most first-class quality.
